re: uBlock origin, Privacy Badger, Ghostery
I'm interested in how/where these might overlap in their functionality, and whether that would cause unintended effects if they're combined
I found PB & Ghostery overlap in some cases, might give false positives with certains sources. For instance, combined PB & Ghostery led to break specific car configuration tools because of some JS scripts getting 404'ed. Other than that, it's more of a memory hog and performance drop issue.
